A 7" TORNEY Patented Jan. 16, 1934 UNITED STATES PATENT oFncr-i SMOKERSPIPE Louis T. Watry, West Allis, Wis.

Application May 12, 1932. Serial No. 610,877 4 Claims. (01. 131-12) Thisinvention relates to smokers pipes and more particularly to a cleaningfeature adapted to be used with a pipe. 1

It is an object of the present invention to provide a pipe having areadily removable absorbent incorporated between the bowl and the stemto remove moisture issuing from the tobacco towards the stem. I

It is a further object of the present invention 19 to produce a pipewhich may be easily cleaned and which will give a dry smoke.

A further object of the present invention is to produce a pipe whichwill cool the smoke before the smoke reaches the mouth of the smoker.

In pipes heretofore designed to dry the smoke previous to it reachingthe smokers mouth, an absorbent material has been placed in the path ofthe smoke and the smoke drawn through it. This has produced a harddrawing pipe, besides presenting difiiculties in the cleaning of thepipe and the replacing of the absorbent material.

It is, therefore, an object to produce a pipe giving a perfectly drysmoke, in which the necessity of drawing the smoke through the absorbentis eliminated, and which will admit of ready replacing of the absorbentmaterial.

These and other objects, the nature of which will become apparent uponconsideration of the following description, are accomplished by means ofa pipe such as illustrated in two preferred forms shown in the drawingand which are described in the accompanying specification, the

invention residing in the particular combination of elements set forthin the appended claims.

In the drawing:

Figure 1 shows a device embodying the present invention, being a crosssectional elevational view thereof;

Figure 2 is a cross section on the line 2--2 of Fig. 1, looking in thedirection of the arrows;

and

Figure 3 is a view similar to Fig. 1 of a modification of the invention.

Referring to the accompanying drawing in which like numerals indicatelike parts throughout the several views, the pipe comprises a bowl 10and a stem 12, the bowl having an aperture 15 therein adapted to befilled with tobacco or other similar combustible material suitable for 0smoking.

The bowl 15 has a counterbore 17 of larger diameter drilled from thebottom of the bowl 10 and substantially concentric with the bowl 15, ashoulder 18 being formed between the bowl 15 and the bore 1'7.

A screen 20 having a mesh sufliciently fine to retain the tobacco withinthe bowlv 15 and of sufficient rigidity to resist deformation due topressure in packing the tobacco in the pipe, fits on the shoulder 18 andis held in place" by a substantially conical funnel 22, the funnel 22being provided with a cylindrical opening 23 in the vertex end of thecone.

Referring to Figs. 1 and 2, a cup-shaped member 26 having a flat plate26' with a concentric 86 aperture therethrough, fits over thecylindrical extension 23 and is attached thereto by soldering or othersuitable means. The cup-shaped member has a downturned peripheral flange28 which fits within a cap, generally designated 30, the cap 30 servingas a closure for the lower end of the counterbore 1'1.

The cap 30 is roughly cup-shaped and may comprise a base plate 32provided with a knob 33 to facilitate removal thereof and an upstand- 78ing cylindrical flange 35. The flange 35 terminates in a plurality offingers 36 having a bead spun about the circumference thereof to fit ina corresponding groove 3'7 in the pipe.

A plurality of instruckbeads 38 are formed about the periphery of theflange 35 and support the cup-shaped member 26 and funnel 22, themembers 26 and 30 cooperating to form an enclosed chamber39 into whichsmoke may enter from the bowl 10 through the extension 23 of the funnel.

One or more pieces of absorbent material 40. such as ordinary blottingpaper, are placed within the cup-shaped cap 30 so that smoke drawnthrough the funnel 22 and the cylindrical extension 23 impinges on theabsorbent paper 40 to remove the moisture therefrom.

The smoke entering through the funnel 22 into the cup-shaped cap 30escapes through apertures 44 in the plate 26' into a bore 45 in the stem12 of the pipe. From the bore 45, the smoke enters the mouthpiece (notshown) and thence to the mouth of the smoker.

In smoking the pipe, smoke is drawn downwardly through the hollow bowl10 and the screen 20 through the suction applied to the stem 12. Thedownward force of the smoke through the funnel 22 and the cylindricalextension 33 causes all of the smoke and particularly the heavy moisturewithin the smoke to continue 1 its downward travel due togravity and theinertia of the moving mass of smoke and moisture to impinge upon theblotting paper or absorbent 40. The blotting paper 40 is preferably madeof any common blotting paper so that when 1 moisture impinges on it,capillary action takes place to draw the moisture into it. Thus, all themoisture is extracted from the smoke and a dry smoke is drawn throughthe apertures 44 to the mouth of the smoker, without having the smokepass through the absorbent material.

-The smoke, in travelling from the bowl 15 to the stem contacts thescreen 20, funnel 22, the cylindrical extension 23 and the cap 26. Bymaking these members of heat absorbing material, such as aluminum orcopper, a large portion of the heat may be withdrawn from the smokeprevious to reaching the mouth of the smoker. By these means, the smokeis not only dried in its passage through the pipe, but is effectivelycooled to give a cool dry smoke, which completely eliminates biteincident to smoking an ordinary pipe.

The modification shown in Fig, 3 is similar to that shown in Figs. 1 and2, except that the cupshaped member 26 is replaced by a disc member 50having apertures 52 therethrough. The disc 52 is attached'to the conicalmember 22 through a central aperture in the disc. The disc restsdirectly on top of the fingers 36, forming an en-= closed chamber53similar to the chamber 39 into which all smoke from the bowl 10 entersand impinges on the blotting paper 40 to have moisture removedtherefrom.

The closure cap 30 may be made the same in both constructions with aplurality of slots 55 lending resiliency to enable the peripheral bead36 to spring inwardly into position in the groove 38.

It will be noted that the fiat plate 26' may be replaced by a conicalmember, if necessary, to bring the outer edge thereof below the stem 45.

When it is desired to clean the pipe, it is necessary only to remove thecap 30 and remove the blotting paper 40 and replace them with cleanblotting papers. Practically the entire moisture in the tobacco smoke isdeposited on the blotting papers 40 due to the proximity of the loweredge of the cylindrical extension 23 of the cone 22 to the blottingpaper. Periodically, the cone 22 and screen 20 may also be removed forcleaning.

Having thus described the invention, it will be realized that there hasbeen provided a relatively simple pipe adapted to both cool and dry thesmoke in its passage through the pipe and it will be realized that theinvention is susceptible to various changes and modifications comingwell within the scope of one skilled in the art, and it is not,therefore, desired to limit the invention to the precise forms hereinshown and described, but only by the scope of the appended claims.
